In this episode host Mark Reggers and guest Kate Cole, Manager of Occupational Health and Hygiene with Ventia resume their discussion and delve deeper into the subject matter of Silica in the workplace.  Silica, a basic component of soil, sand and rock is one of the most widespread minerals on earth existing in both crystalline and amorphous form. The crystalline form, which is more of a health concern, can be found in many common construction and building materials including: sand, stone, cement, concrete, asphalt, brick, tile, grout, mortar and drywall. Crystalline silica can become airborne during sanding, crushing, cutting, drilling and chipping. These tiny particles can be easily inhaled and travel deep into your lungs, repeated and long-term exposures have been linked to Silicosis and Lung Cancer. Some deadly respiratory illnesses caused by work can take up to 20 years to develop.
